摘要： 为解决传统环氧富锌涂料锌粉含量过高导致的涂层起泡、缩孔、机械性能差等问题，对涂料配方进行优化筛选，并添加超高导电性的石墨烯粉体，制备了一种高性能低锌粉含量环氧防腐涂料。并对涂层的附着力、耐冲击性、耐水性、耐中性盐雾性及耐湿热性等性能进行测试。结果表明：用 19. 35%环氧树脂 E-20、2. 15%聚酰胺加成物固化剂、 45%锌粉、 10%滑石粉、 2%触变剂 881B、1%流平剂 AFCONA-3777、0. 5%石墨烯、 20%稀释剂 2033，制备的环氧石墨烯低锌防腐涂料，涂层具有较高的耐冲击性（ 50cm）、附着力（ 16 MPa）和优异的耐盐雾性（ 2 000 h）、耐水性（ 2 000 h）和耐湿热性（2 000 h），可应用于苛刻腐蚀环境。

Abstract: In order to solve the problems such as blistering，shrinkage and poormechanical performance caused by high content of zinc powder in traditional epoxy zinc-richcoatings，the coating formula was optimized and screened. And adding ultra-high conductivitygraphene powder to develop a high-performance graphenel/epoxy coatings with low content ofzinc. The adhesion，impact resistance，water resistance，neutral salt spray resistance and moisture and heat resistance of the coating were tested. The results showed that the graphene/epoxy anticorrosion coatings with low content of zinc prepared by using 19. 35%E-20 epoxy resin，2. 15% polyamide additive curing agent，45% zinc powder，10% talcum powder，2% thixotropic agent 881B，1% leveling agent AFCONA-3777，0. 5% graphene and 20% diluent 2033，the coatings had excellent impact resistance（50 cm），adhesion（16 MPa），
excellent salt spray resistance（2 000 h），water resistance（2 000 h）and damp heat resistance（2 000 h），which could be used in harsh corrosive environment.
